I want to spawn sprites in random spots outside of the view. Then I want each sprite to move towards the center of the screen and out the other side.
Anyone have a solution? I'm not sure how to accomplish this.
Here's my code:
I didn't realize it was as simple as spawning the sprites at a certain point, and then telling them to move to another point. I've learned so much in the two days since I asked this question.

I am trying to make a 3D jumping game where my character is standing still and the objects and background are moving towards him to make it seem like he is running. I have a bunch of models for buildings that I am instantiating using an empty game object that I use as a spawner. I want the buildings to spawn one after each other, so whenever one building has moved far enough and left enough space the next one should spawn. I first tried to do this with InvokeRepeating, but the buildings are different widths so it does not work well with a constant repeat rate. I then tried to put a collider on my spawner and spawn a building whenever the spawner collider is not colliding with anything, but it seems to just spawn buildings infinitely. Is there a way to fix this or a better way to do this?
There are many different ways of doing this.
The most straightforward is possibly to let each building spawn the next one, as I assume they each know how wide they are and thus when it's time for the next.
Well , first things first your problem is looking more like a design problem. I would recommend searching things like "procedural world building" , also object pooling. There is lots of examples of runner games that do what you describe.
You can check the palyer position to instantiate , you can create parts of the road as prefabs , make lots and lots of prefabs and instantiate them as you go etc. The question you asked is simply too wide to give an actual answer. So if you have any more spesific questions , it'll be nice to answer !

Hello everyone!
I had a plan to make all of these cubes rotate around in a conveyor belt fashion.
My first thought was to animate each one to rotate around. I haven't done that option because I feel like that would overall cause issues.
My second thought was to make a bunch of empty lerp points, have the objects lerp around and have a trigger on the end set their rotation to about the right angle of the black conveyor belt center.
These will most likely both work, but may take more effort than is necessary.
Is there a better way to do this? Does Unity have a feature that I am unaware of?
Thank you for your help!
I am making a multiplayer top down 2D game with 3d elements. All my movement, healthbars and basic functionality is working flawlessly even while hosted and playing on a server, node.js socket.io. However In this game it is possible to move the camera like in Realm of the mad god.
in case you are in doubt here is a video: https://youtu.be/4tdcxl3aZ0c?t=31s
This of course means that the players can end up being upside down with regards to each other and I cannot find a solution that works in all regards to make sure the sprites of the other players are always facing the correct direction with regards to their movement.
I have made several solution to this problem which cover most scenarios but while play testing other things we always end up noticing that the sprites sometimes face the wrong directions. So I am wondering if anyone has an answer, the logic, the fixing this problem.
Things I have tried:
Adding a gameobject to the camera to which all sprites asses their change in distance and determine their facing direction based off that information. (this leads to the players sometimes flipping erratically when the camera is moved and they as well are moving as sometimes they may be moving slower and there although moving left the camera approaches from the right and that flips them)
Adding a gameobject to the world which allows all sprites to have a fixed point to which they can measure their change in distance and therefore also know what direction to face (this worked somewhat better as they always know what direction they have to face, however once the player is upside down everything is inverted)
Emitting to the other players wether I am upside down or not in order to try to reinvert the above solution in the case I am upside down. (I could not find a good way to do this, and it got me thinking that this must be a problem people have fixed before many times and perhaps someone know of a good solution that works.)
thank you all for your input.
I seem to have found a solution for this issue that works decently well. Keeping in mind that I do not want to have the server being involved in this and I would rather have each individual sprite know its direction rather that have something heavy trying to determine this logic I came up with the following solution. May not be the best but it works. Still very keen to hear other solutions.
On my main character I have a switch case, which changes depending on the players rotation in the world. I need this switch case anyway for fixing (http://answers.unity3d.com/questions/1348301/trying-to-change-the-cameratransparencysortaxis-to.html?childToView=1348316#answer-1348316) that issue.
As the cases change I simply place the gameobject that I want the sprites to compare their distance to at 1 of 4 positions. YPos, YNeg, XPos, XNeg. Meaning that the sprite now determines its facing direction based on a gameobject that is placed in accordance with the Players position. without having to place it on the camera.
I will update if during further play tests this gives me trouble but thus far it works in the all the cases I need it to.
Still very willing to hear other solutions to this problem.
Thank you.
I want to create a cclayer with 4-5 flying objects, flying in random directions on screen. I also want those flying objects transparent to each other, which means they can fly through each other.
What I can think of Ways to do:
With Box2D
Create a box2d world with 0 gravity. and add Polygon static ground around the edges of the screen.
Give an initial force to each of the flying objects, let them flying around and reflect on the grounds.
Problems: Objects still rest down after sometime.. Don't know why. Objects collide with each other, don't know how to make them fly through each other.
Without Box2D
use CCMove for each objects, detect if they reach edge of the screen, calculate new path for their move..
Can someone point me a direction, which way is easier? Thanks a lot.
If you have to handle complex collisions - go with Box2d. If your collisions are simple - handle them yourself.
I have a game world that's much bigger than the view port, the main character stays in the center of the view port at all times and the background layer is moved around to give the impression of the character moving. I want to make it so that the game world wraps, meaning if the the character keeps traveling either left or right they will eventually end up back at the starting position. There will be moving entities in the game world so the biggest problem I foresee is that if you go to the far right of the map you should be able to see any of the moving entities that are within the first small section of the far left of the map.
I've thought a bit about this and any solution I've come up with seems far too complicated. Like creating two identical game worlds side by side and moving them around accordingly. I live in hope that there is an elegant solution to this. Any expertise you can share would be greatly appreciated.
I'm using cocos2d on the iPhone just in case that makes any difference.
An example might be to have an x,y offset for your camera, and a multidimensional array of sprite objects.
As the player moves, the offset value changes, e.g., xMove = -1.4 and yMove = +2.6.
Then you would iterate and change the positions of all the tiles by that amount.
Next, you would identify the sprites that are too far away from the center of the screen (0,0) and re-position them to the opposite side, so they will always be visible.
This would all be done on the same scheduled 'tick' so no graphical artifacts occur.
I'm pretty surprised no one has made a wrappable tile map yet for cocos2d.
I can't give cocos2d specific advice, but I would say the most common way to do this is to create one game world, draw (parts of it) multiple times and make sure that your logic for things like collisions and AI checks for wrap-around where appropriate.
So if your player character is close to the corner of the world, you'd draw the world four times with different offsets. This needn't actually draw every single thing in the world four times any more than you would normally need to draw the entire world when only a small part of it is on-screen.
